CHARLES WIEBKE, OF NEWARK, NEW JERSEY.

BUTTON-COVE RING- MACHINE.

To all whom it may concern:

Be it known that 1, CHARLES VVIEBKE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Button-CoveringMachines, of which the following is a specification, reference being hadtherein to the accompanying drawings, forming a part thereof.

My invention relates to button covering machines wherein a mold or formis covered by the winding of silk or other suitable covering materialthereon, and has for its objects the ready adjustment of the positionsof the parts of the machine and also the ready adjustment of the speedof the niold carrying part.

My invention also has for its objects simplicity of construction, easeand reliability of operation.

Other objects of my invention will appear from the following descriptionof the machine embodying my invention illustrated in the accompanyingdrawings.

I will now describe such construction and will thereafter point out myinvention in claims.

Figure 1 is an end elevation of the button covering machine, partly insection. hig. 1 is a detail elevation of the flat springs of the tensiondevice. Fig. 2 is a front side elevation of the machine. Fig. 3 is aplan view. Fig. 4 is a detail plan view, partly in section, of the moldactuating mechanism. Figs. 5 and 6 are enlarged views of the swivelingbearing for the mold spindle. Fig. 7 is an enlarged view of the knurledfriction wheel. Fig. 8 is an enlarged rear face view of a portion of thegrooved friction disk.

The several parts of the machine are shown as supported upon a base 1.The standard 2 for the winding flier is bolted to this base betweenguide-ways on the base in the usual manner and is forked at its upperend, and the flier spindle 5 is removably and adjustably held in asleeve 9 having bearings in these forks 3 and 4, a set-screw 14 clampingthe flier spindle in desired position in the sleeve. The flier spindle 5is provided at its front end with an enlarged portion 6 in which theshank or longitudinal portion of the flier 7 is fitted in a bore at oneside of the axis of the flier spindle, and the flier is removably andadjustably held in this enlarged portion 6 by a set-screw 13. The outerportion of the flier is curved through a semicircle and is Specificationof Letters Patent.

provided with a hook or loop 8 at the end of curved portion and thefront end of the ier.

A pulley 10 is provided upon the sleeve 9 of the fiier spindle 5, andthis pulley receives motion from a large driving pulley 12 by means of acord 11 passing over both pulleys. The driving pulley 12 is fitted uponthe driving shaft 15, and the driving shaft rotates in bearings providedat the upper ends of standards 16, 17 which extend upward from the baseand are bolted to the base between guide-ways in the usual manner. Ahand crank 18 is shown secured upon the front end of the shaft formanually operating the machine.

The button or mold carrier comprises a mold spindle 23, the lowerportion of which is cylindrical and the upper portion of which isgradually tapered to a point so that the mold may be readily insertedthereon and pressed downward until it is tightly gripped by the taperedsurface of the spindle and molds having holes of different sizes may becarried upon the mold spindle. The mold 49 is shown upon the spindle inFigs. 1 and 3. The cylindrical part of the mold s indle 23 is removablyand adjustably he d within a sleeve 28 being clamped in the position towhich it is adjusted by a set-screw 31, and this sleeve 28 is rotatablyheld in two arms 25, 25, on a swiveling frame comprising these arms anda ring 24 (Figs. 5 and 6) fitted to swivel on a boss 20 of a bracket 19,this bracket being shown as secured to and projecting forward from thestandard 2, which carries the flier. The movement of this swivelingframe 24, 25, upon the bracket 19, permits the axis of the mold carrierto be inclined at the desired angle for holding the mold relatively tothe flier. A set-screw 39 holds the swiveling frame in the position towhich it has been adjusted.

The mold carrier is actuated from the driving shaft throughmotiontransmitting means including a longitudinally arrangedintermediate shaft 21 which at its end in proximity to the mold carrierrotates in a bearing in the boss of the bracket 19, and has secured uponit at its end a beveled gear 26 which meshes with a beveled gear 27secured upon the sleeve 28 of the mold carrier. The intermediate shaft21 at. its other end terminates just below the driving shaft 15 androtates in a reduced bearing in a spring pin 45, which projects rearwardfrom a bearing stud 42 of a driving disk 30 and which extends throughthis stud and ro jects forward therefrom and has ahe ica'l spring 47surrounding it. The spring bears at its rear end against the front endofthe stud 42 and at its front end against the rear The'feeding andguiding means for the silk or other-covering material comprise a spoolface 'of adjusting '1'iut48 ontli'e' spring pin 45. hearing for theinterme iate shaft 21; and

to provide for the movement of the shaft thusperrnitted theshaft-bearings are loosely fitted. The purpose of the yielding means forcarrying theintermediate shaft 21 is to permit the actuation of thisshaft byengagement with the driving disk 30- ofa motionreceiving disk 29carried by this shaft, and to permit the motion-receiving disk 29 to beadjusted to engage the driving disk 30 at different distances from theaxis of the disk so as to vary the speed imparted to the intermediateshaft from the driving disk. The motionreceiving disk 29-is free toslide longitudinally upon the intermediate shaft 21 its boss'h-aving aset-screw 32 which entersa longitudinal slot 33 in the intermediateshaft so as to hold it rotatively to the shaft, but permit it to movelongitudinally upon the shaft. The rear face of the driving disk 3.0 isprovided with a number of concentric grooves 30 and the motion-receivingdisk 29 is tapered to an edge and knurled at its periphery so that itwill enter any one of these grooves and} under tension ofthe spring 47will be held tightly therein-againstthe driving disk so as to berotatedby the drivingdisk.* The motion-receiving disk 29'is separately shown inFig. 7. This thin edge permits the'circula'r grooves 30 in the drivingdisk to be arranged quite "c'losely-together and thus assures an evenadjustment. 1 To shift it fromone groove to another it is only;necessary to press the-"spring pin'4-5 backward, =thereby compressingthe spring-47 and motion receivingdisk backward away from the rear faceof thedriving disk and then to slide the motion-receiving disklongitudinally on the intermediate shaft-to thedesired new position ofadjustment.

vUpon releasing the spring pin the spring restores the motion-receivingdiskto engagement with the driving disk'in the groove thereof to whichit hafs-been'adjusted and the motion receiving disk will be held in suchan in-ten groove until moved therefrom by tional act of adjustment.

To relieve the bearing of thedriving disk 30 from the thrust of themotion receivingdisk, an idle roller 34 bears-against thefront face'ofthedriving disk in proximity t'o the outer periphery of this disk, andthis idle roller is carried ona stud 35secured-to; the standard; 16,which carries thebe'aring stud 42 of the driving disk. The bearing stud42 is provided with anannular collar 43 and is secured inplaoe by a nut44. The driving Thus the spring 47' ro'vide's a yielding disk 30 isshown as actuated from the driving shaft 15 through a toothed pinion 41on the'driving shaft meshing in an intermediate gear wheel 37 and atoothed pinion 38 secured to the gear Wheel 37 meshing in the teeth onthe periphery of the driving disk 30.

50, which rotates upon a stud 51 mounted upon an arm 52 secured to andextending rearwardlyfroni the base. To ease the unwinding of the silk,arotary flier is provided :comprising an arm 53 carried by a hub 56fitted to rotate freely upon the upper'portion of the stud 51', this arm53 havingian epe- 55 at its free end which guides the silk in theunwinding movement thereof.- The silk passes from the rotating eye155upward'and over a guide-loop in an arm 60 extending up from the frameand then downward and through an eye in an arm 61 extending upward froman arm 58' projecting rearward from the standard Thesilk then-passesthrough a 'loopSof the flier, and from the loop 8 of the flier it passesaround the mold 49 upon which it is wound by the flier to cover the-mold.

An exact adjustment of the flier and mold carrieris required for theproper covering of the mold. This may be very readily effected as theflier; spindle 5 may be adjusted'longitudinally or S axially in itscarrying sleeve 9 by manipulation-of the set-screw '14, and the radiallength of the flier may be independent-liy adjusted by -manipulation ofthe setscrew-13; and the mold spindle may be ad justed longitudinally oraxially inits carrying sleeve by manipulation of the screw 31, and theangular position of the mold carrier may be adjusted by manipulation ofthe set-screw 39; The aim-dependence of these several means ofadjustment;permits eachadjust- -ment to be performed without-disturbancespring pin 47 and motion-receiving disk 29 in the manner alreadydescribed.

7 It is obvious that various modifications may be made in theconstruction shown and above particularly described within the principleand scope of my invention.
